Hey there Havani,
Sorry for the late response. Indeed the error is Internet Explorer is the culprit. Calling it via VBS can cause it to get stuck as a background process and error out in this scenario. Best case is to track down all open instances in task manager or do a full reboot. Outside of that, opening and closing IE a few times usually works for me when that happens.
I am looking for another VB friendly browser with the impending doom of IE, however they seem few and far between.
